My recollections of those smoky daze 30 years ago tells me that I prefered the JBL at the time. Punchier mid bass, more mids and highs. The speaker of choice for a whole generation of rockers in the early 70's, particularly when mated to a Marantz 2270 or something similar. DSOTM sounded great.

Of course, times and tastes change and my preferences might be different today.
